Decontamination with hydrogen peroxide

Fumigation with hydrogen peroxide (H₂O₂) is used to decontaminate clean rooms, laboratories, safety cabinets and isolators, and represents a fast and affordable alternative to decontamination with formaldehyde. Laboratory testing has shown the H₂O₂ method to be effective when compared with the formaldehyde method. In addition, hydrogen peroxide carries fewer health risks than formaldehyde.

Key benefits at a glance:

• Much lower health risks than formaldehyde
• Safe and effective
• Fast and affordable
• Residue-free method with no need for further cleaning
• Validated process
• Method reviewed and certified by the German public health institute RKI
• Compliant with the FDA’s 21 CFR Part 11

Rapid and clean: decontamination with the FASTER NHP System

Hydrogen peroxide is a largely stable compound of hydrogen and oxygen, found in liquid form. It has strong oxidising properties and makes an excellent decontamination and sterilisation agent thanks to its broad range of effects. Our method involves vaporising a hydrogen peroxide solution and blasting this into the area which is to be cleaned. It only takes around one to two hours to completely decontaminate a safety cabinet with this method, which is statistically proven to reduce the number of germs by 1,000,000 times (6 log reduction).

We are using the most high-performance generator available on the market — the FASTER NHP generator, a mobile unit produced by the world’s largest manufacturer of microbiological safety cabinets and isolators.

The generator is highly mobile and can be quickly connected to the safety cabinet or isolator, which will then be decontaminated using H₂O₂ in a closed-loop system. All surfaces of the work area, as well as areas such as the return air duct, ventilators and filter, are coated evenly with vaporised H₂O₂. The quantity of hydrogen peroxide used is calculated based on the size of each individual machine. The fumigation cycle is checked using chemical and biological indicators (CI and BI). With the FASTER NHP system, even rooms up to 500 m³ can be easily decontaminated.

A slight negative pressure is maintained during the process to guarantee that no H₂O₂ can escape. In addition, the surrounding area is monitored by a Dräger Polytron measuring instrument. Once decontamination is complete, a catalytic converter breaks the H₂O₂ down into the harmless substances of oxygen and water, which are then carried off via a special HEPA H14 filter.
